3.4 The Four Modes for Synchronizing with the CAM/CMOS – 2K.LS
There are four synchronization modes as explained below and summarized in Table 3.4.1 below.
Freerunning Mode is described below in (Figure 3.4.2). In this mode, the camera is not triggered;
instead it drives the world around it. It is the default mode set and shipped by the factory.
ExSync Line Synchronization is described below (Figure 3.4.3). The target asychronously
synchronizes the CAM/CMOS – 2K.LS from an external trigger via the ExSync line. The user
selects ExSync Synchronization or any of the modes via the camera command set. In this mode,
start of integration is asynchronously controllable with ExSync, and continues until the end of the
line period.
ExSync Line Synchronization with Programmable Integration Time is described in (Figure
3.4.4). This mode is similar to ExSync Synchronization, but in addition, in this mode the user can
program the duration of integration over the serial interface to be less than to the end of the line
period.
